I would like to order the following drop-in with the new Nichia 219 LED:
$35 Nichia 219 (4500k 92CRI Neutral)
$5 Thermal Potting & Copper Tape
$5 Intl. Shipping
Specs: 1 level 2.8 - 6 volts / LOP reflector / driven a bit lower if there's a choice... I prefer more runtime and good heat management over peak levels of brightness.
